[Affected devices] Frequent head unload under Linux

[Affected devices] Frequent head unload under Linux

[Diego Rondini]

As asked in this page:
http://ata.wiki.kernel.org/index.php/Known_issues
I report you of two notebook with this issue.

Unfortunately I haven't access to these notebooks anymore (I installed 
Linux in an install party) so I cannot attach the output of the several 
commands.

Both of them did very frequent unloads, for sure more than 5 per minute, 
but maybe even more. So that's more than 180 per hour!

The notebook were very different, the first was a 5 years old HP Compaq 
NX 9005 with a 30GB drive:

Probably the drive was a Hitachi model:

The other one was a brand new HP Compaq F760EL with a 120GB drive, but I 
didn't managed to know which kind of drive it's using...

Sorry for the incomplete informations provided, hope it's better than 
nothing.

Bye,
Diego

Thanks but I can't really add the entry without knowing more
information.  I'm trying to come up with more automatic solution so all
these may be able to go away in some time.

Thanks.
